sue,
if i notice low humidity problems with one of my tanks sometimes an easy solution is just to place the water dish closer to the heat source. changing the placement of the water dish can change the humidity up or down as much as 20% i've noticed. this also keeps the substrate dryer than misting. i live in new york where the winters can be quite dry and it often leads to shedding problems so i also normally have a humidifier going in the winter in my snake room to keep the humidity up around 50-60%. hope this helps.. jim
